2 . Left-handed people can find it inconvenient to do certain things, writing in a notebook for example.     1     Research found that they were over-represented (任职人数过多的) among fighters in combat sports. Left-handed fighters also had higher chances to win. This confirms the fighter theory.

    2     The explanation is that the two brain spheres of left-handers are more strongly connected, strengthening memorial ability.

Being left-handed might be a factor in mathematical ability. An Italian study found that for simple arithmetic there was little difference between right- and left-handed performance.     3     No one understands the reason for this.

    4     In one study, researchers showed the participants columns of abstract illustrations and asked them which ones they would prefer. Left-handed people were more likely to prefer the images on the left. Right-handed people preferred the ones on the right. Both groups disliked stuff on their opposite side.

Left-handers are also over-represented in professional, interactive sports. Researchers have looked at the influence of being left-handed on performance and interactive sports.     5     So if you have a left-handed child, you should encourage them to play table tennis, baseball and tennis. Being left-handed maximizes their chances of success in these sports.

3 . Santa Rosa National Park is the first national park designated in Costa Rica. It was created not to preserve land but to save a building, La Casona, which was once destroyed by fire, but has been rebuilt to its original likeness.

In addition to La Casona, Santa Rosa National Park protects a multitude of ecosystems including marshlands and mangroves. Many endangered animals also live here, with over 100 mammals and 250 birds recorded within the park.

Playa Nancite is the most popular beach for sea turtle. Entry to the beach is restricted for protection, but entry can be obtained from park headquarters.

There are two different sectors within Santa Rosa National Park. The Santa Rosa Sector is frequently visited for its notable attractions including access to La Casona. The other sector, Murcielago is not accessible via the Santa Rosa Sector.

There are several different hiking trails within the park. We recommend bringing closed-toed hiking shoes, a hat, sunscreen, bug spray and water.

We highly recommend exploring Santa Rosa National Park led by an expert naturalist guide. The park entrance fee is $15 per adult and $5 per child age 6 — 12. The park is open from 8:00 am to 3:30 pm every day.

4 . In 2019, after retiring from her career as a social worker, Ane Freed - Kernis decided to build a home workshop and devote all of her free time to stone carving. “I might be covered head to to e in dust but I’m happy — it was something I needed more of in my life when I hit 60,” she says.

This appeal has its origins in Freed - Kernis’ childhood. Growing up on her father’s farm in Denmark, she used to wander through the fields with her eyes fixed on the ground, looking for stones to add to her collection. “I’ve always been drawn to the shapes and textures (质地) of stones,” she says.

After moving to England in 1977 and training as a social worker, Freed - Kernis soon became occupied with her busy career and the demands of raising her son. Stones were the last thing on her mind, until her father died in 2005. “He took a stone carving course in his retirement, and I always thought stone seemed so fun but never had the time to look into it myself,” she says. “After he died, I became determined to learn in his honour.”

Signing up for a week-long stone carving course at Yorkshire Sculpture Park, Freed-Kernis began to learn how to turn a block of rock into well-designed shapes. “It was really scary at the start because you would spend hours just hammering (锤打).”

Now 65, Freed-Kernis has a thriving small business built largely through word of mouth. She creates 12 to 15 pieces a year that can take anywhere from a few days to three weeks to complete, while her prices range from £ 200 to £ 3,000. “I’m making smaller ones,” she says. “I don’t have to depend on the money much, so I want to keep prices in the range that people can afford, mainly just covering costs and labour (劳动力).”

5 . In San Francisco, a large group of sea lions move themselves out of the bay waters and hang out on PIER 39, which is a popular tourist destination. According to dock (码头) officials, this is the most sea lions seen in the region in 15 years.

“Over 1,000 sea lions have been counted this week,” PIER 39 harbormaster Sheila Chandor told many different media. “The surge in sea lions is usually a good sign of their strong population and healthy living environment,” said Adam Ratner, Director of Conservation Engagement at the Marine Mammal (海洋哺乳动物) Center in Sausalito, California.

“California sea lions are sentinels (哨兵) of the ocean,” Ratner said. Their population to some extent reflects the health of the ocean. Therefore, seeing a large number of California sea lions is clearly a good thing.

For nearly 35 years, the slippery (滑的) residents have been a star attraction for tourists. That autumn in 1989, PIER 39 had just been repaired, but the ships had not yet been moved back. At that moment, the sea lions unexpected arrival not only attracted fans but also created enemies. According to a website, some dock residents and workers were scared away by the strong and very unpleasant smell and noise of their new neighbors, while others saw these animals as a bright spot after the destructive Loma Prieta earthquake.

The officials sought help from the Marine Mammal Center to find a way to deal with sea lions. Ratner said that the final decision is to let the sea lions stay and coexist with humans. “The fact proves that this is really a good thing,” he said. “This is just a proof of how we can truly work together and think about how we can share our coasts with marine mammals and other wildlife in a way that benefits all the parties involved.”

6 . Self Love

Our failure to love ourselves is that we have been taught to be selfless from the start of time. Self-love is not selfish. It only helps us better understand which sacrifices are worth making! Let’s explore the key elements that contribute to it.

Self-Acceptance

You have to truly accept who you are. And by acceptance, I do not mean just your strengths, you have to recognize your weaknesses, too.     1     The core of self-acceptance is to be authentic with yourself.

    2    

It is a good thing to be compassionate about your environment but in the process, don’t forget to be compassionate with yourself, too. Forgive yourself for the mistakes that you make, the goals that you fail, or whenever you face a setback. Treat yourself with the same level of empathy you would offer to someone you love the most.

Self-Care

Has anyone of us ever asked ourselves who we should be caring for the most in the world? Our parents? Family? Friends? Relations? I will tell you a simple answer. Ourselves! The expectation of waiting for someone else to care for you is delusional (妄想的).     3     Look after your relations but do not forget to look after yourself. You can only give something that you have in abundance.

Boundaries

You have to love and respect yourself enough not to let people use and abuse you.     4     You have to let people clearly know how you won’t tolerate being treated. You have to let them know how you expect to be treated.

Emotional Availability

When you have the capacity to take care of your own emotions, you become emotionally stable. This stability allows you to better empathize (同理心) with and understand your partner’s experiences and emotions.     5    

8 . Though March remains cold, the return of the bright and gently warming sun wakes winter-sleeping plants and seeds from their sleep. Today, I’m out here to sow seeds for the summer garden: tomatoes, peas, cucumbers. All of these plants are easy to grow, pretty and tasty.

Initially, I plant the little tomato seeds into rows in a single seed plate, each variety divided by a sideways stick and labelled. Then I cover a fine layer of soil over them and put the tray in a basin of water to make the compost(堆肥) wet.

For tomatoes, it is not yet warm enough for reliable growing outdoors. In the main, a warm home is a good place to get seeds going, as they don’t necessarily need a great deal of light at this stage. In a few weeks, when their two young leaves have come out, I will gently dig them out. Softly pick up one of their delicate leaves between finger and thumb, I’ll slip a pencil below their young roots to carefully dig the plant from its birthplace.

I’ll then place the seedling in a, pot to grow, big, and strong, and begin to feed, the plants with a liquid from brewed(发酵) chicken waste. These tomatoes, being tender, will stay in my house until early May then settle into their forever home in the unheated greenhouse.

Despite there now being enough light for tender plants to grow outside, it is still too cold for them. A sunny balcony, warm glasshouse or passageway will do them well until the frosts pass, and day and night temperatures consistently reach 8—10℃.

Learning to be guided by cues from the wild can deepen our relationship with the living world, allowing us to experience ourselves as part of rather than separate from the rhythms of life on Earth.

10 . A recent study suggests that for young soccer players, participating in repetitive technical training activities involving heading during practice may result in more total head impacts, but playing in actual soccer games may cause greater magnitude (程度) head impacts.

“Headers are a fundamental component to the sport of soccer. Therefore, it is important to understand differences in header frequency and magnitude between practice and game settings,” said study author Jillian Urban, PhD, from Wake Forest School of Medicine. “Practices are easier to change than games. Therefore, understanding how we can restructure practice to reduce head impact exposure while teaching fundamental skills is critical to improving head impact safety in the sport.”

The study followed eight soccer players who were aged 14 and 15 for two seasons. Players wore a sensor (传感器) during all practices and games. Researchers recorded all activities on the field with a camera, and identified each time head contact was made.

Head impact exposure was evaluated in terms of peak head motion and impacts, or impact rate per player per hour. Researchers then compared impact rates across different activity types.

Researchers amazingly found that technical drills like heading the ball and practicing ball-control, were associated with an average impact rate of 13.7 head impacts per player per hour. Team interaction activities such as small-sided games in practice were related to an average impact rate of 0.5 head impacts per player per hour, which was slightly lower than the 1.3 head impacts observed during actual games.

The study also revealed that games were associated with the highest numbers of average rotational (旋转) head motion, which signified the greatest magnitude head impacts. However, technical training recorded the lowest numbers.

“If the goal is to reduce the number of head impacts a young soccer player may get on the field, our findings suggest the best way may be to rearrange technical training practices,” said Urban. “However, if the goal is to reduce the likelihood of players sustaining head impacts of greater magnitude, then the best bet may be to look at factors related to high-magnitude head impacts that can occur during games.” A limitation of the study is the small number of players involved.
